    • Introduction au CND (2.0 crédits ECTS)
    • Son et patrimoine (2.0 crédits ECTS)
  • Acoustics I (6.0 crédits ECTS)Description :

    Présentation

    Four lectures (around 10 hours) and four series of exercises related to each lecture (around 30 hours). The titles of lecture are (see lecture notes on UMTICE for more details): Fundamental equations of acoustics (in fluids) - Plane waves - Cylindrical and spherical waves. - Guided waves - Modal analysis

    
    Objectifs :

    Objectifs

    The main objective of this course is that students have solid backgrounds on fundamental aspects of acoustics including : The fundamental equations of acoustics (backgrounds in fluid mechanics and thermodynamics) - The derivation of the wave equation (mostly for the usual case of uniform fluids at rest) - The acoustics of the gas column (resonance, free oscillations, coupling etc..) - Reflexion, transmission, and diffraction phenomena - Guided waves and the modal theory - Spherical and cylindrical waves (sound radiation, diffraction, guided waves in cylindrical ducts, etc...)

    
    Pré-requis nécessaires :

    Conditions d'admission

    Having backgrounds in acoustics is obviously a good point, but it is not es- sential. Having solid backgrounds in mathematics is essential. This includes : trigonometry, integration/derivation, asymptotic expansions of usual functions, solving of O.D.E., functions of multiple variables, vector analysis and operators (in various systems of coordinates) , linear algebra ... Reminders of useful formula will be provided, and exercise will be treated, but you need to know that we can’t ignore mathematics in this course...
